Line coilers take the work out of re-spooling any reel.  Simply remove the top and slide any spool of fishing line on the coiler assembly.  Replace the top and tighten onto the spool for the correct tension you want on your reel.  Re-spooling under tension is very important and prevents a loose spool of line which digs into your reel and makes many twists.  Comes complete with a suction cup mount, very versatile and can move from boat to tackle room easily.  Accommodates all size spools of line.  5 year warranty, longest in the industry.
